a U.S. Department of Transportation (USDOT), National Highway
Traffic Safety Administration (NHTSA) rounds its injury and crash data to the
nearest thousand before publishing them, but it calculates injury rates using
the unrounded data. NHTSA also
calculates fatality and injury rates using vehicle-miles expressed to a
higher level of precision than shown here.

b NHTSA typically revises its
most recent annual estimates the following year. The data here remain unrevised from the
date of publication, but may be revised in the future.

NOTE

The
injury and crash data in this table are from NHTSA's General Estimates System
(GES). The data from the GES, which began operation in 1988, are obtained
from a nationally representative probability sample selected from all
police-reported crashes. The GES sample includes only crashes where a police
accident report was completed and the crash resulted in property damage,
injury, or death. The resulting figures do not take into account crashes that
were not reported to the police or that did not result in property
damage.
